season and limited rainfall, concentrated in a short period of time. Therefore, coccidioidomycosis presents a limited geographic distribution, and transmission is restricted to a few months of the year. (2) The fungus disseminates as arthroconidia and is inhaled together with soil dust. In Brazil, armadillo hunting is an activity that carries a significant risk for infection.Pulmonary coccidioidomycosis is typically self-limiting but can evolve to chronicity and dissemination.

Coccidioidomycosis is mainly restricted to areas with arid climate, alkaline soil and low rainfall. Consequently, most of the reported cases in Brazil have occurred in the northeastern region. We report three cases of pulmonary coccidioidomycosis occurring between 2005 and 2006 in an endemic area in the state of Ceará, Brazil. The three patients were immunocompetent adult males, hunters of armadillos (Dasypus novemcinctus), with complaints of cough, fever, dyspnea and pleuritic pain. All three patients presented pulmonary involvement, and one also presented cutaneous lesions. Chest X-rays and CT scans of the patients revealed characteristic coccidioidomycosis lesions. The diagnosis was confirmed by serological testing. All of the patients evolved to cure after antifungal treatment.Keywords: Coccidioidomycosis; Lung diseases, fungal; Coccidioides. ResumoA coccidioidomicose, uma doença fúngica adquirida através da inalação do agente Coccidioides sp. sob a forma de artroconídio, foi pela primeira vez descrita em 1894. Restringe-se principalmente a áreas de clima árido, solo alcalino e regiões de baixo índice pluviométrico. Não por acaso, a maioria dos casos descritos no Brasil ocorreu na região Nordeste. Relatam-se três casos de coccidioidomicose pulmonar ocorridos nos anos de 2005 e 2006, em zona endêmica no interior do Ceará. Todos eram homens imunocompetentes de idade adulta, adeptos à prática de caça a tatus (Dasypus novemcinctus) com queixas de tosse, febre, dispneia e dor pleurítica. Houve evoluções com comprometimento pulmonar e lesão cutânea foi observada em apenas um paciente. Todos apresentaram radiografia e TC de tórax com lesões características da coccidioidomicose. O diagnóstico foi confirmado através de teste sorológico. Todos evoluíram para cura após tratamento com antifúngico.
Protein-losing enteropathy is rarely seen in patients with systemic lupus erythematosus. This clinical condition should be suspected in the presence of persistent hypoalbuminemia despite normal liver function, adequate protein intake, and no signifi cant proteinuria. We report the case of a 48-year-old female with weight loss, cavity effusions (ascites and pleural effusion), and lower extremity edema. The diagnosis of lupus was established based on the presence of lymphopenia, proteinuria, ANA, and positive autoantibodies (anti-Sm, anti-DNA, and anti-Ro). Because hypoalbuminemia persisted even with corticosteroid therapy at the dose of 1 mg/kg, protein-losing enteropathy was diagnosed by use of Tc-99m albumin scintigraphy. After adding azathioprine to the treatment, the symptoms subsided and serum albumin levels improved.
Background Pulmonary hemosiderosis is a rare disease that may be idiopathic or have a secondary etiology, such as mitral stenosis. The disease is a clinical and functional consequence of iron overload in the lungs in the form of hemosiderin. The diagnosis should be considered in patients with miliary nodules on chest tomography. Case presentation We report a case of a 30-year-old man with severe mitral stenosis who presented with chest pain and dyspnea. High-resolution chest tomography showed bilateral centrilobular micronodules. The diagnosis of pulmonary hemosiderosis secondary to mitral stenosis was suggested by transbronchial biopsy. Conclusion The diagnosis of idiopathic pulmonary hemosiderosis requires the exclusion of other etiologies of alveolar hemorrhage, including infections and vasculitis. One possible etiology is mitral stenosis.
